Tanalian Falls
Tanalian Falls drops about 30 feet over an ancient lava cliff on the Tanalian River near Port Alsworth, reached by a forested trail in Lake Clark National Park. The route passes birch and spruce groves with views of Lake Clark before the falls.
Before you go
Waterfalls are hazardous by nature — wet rock, cold water, and unstable edges — and flow varies enormously with season and recent rain. Trail figures here describe the route as documented, not conditions today. Check Lake Clark National Park & Preserve (NPS) for closures and current conditions, and confirm land status before setting out.
Frequently Asked Questions
Tanalian Falls drops about 30 feet. That makes it the 564th-tallest documented waterfall in this inventory, taller than roughly 23% of the falls listed here. Height comes from published land-manager and survey records, not from our own measurement.
The Tanalian Falls Trail reaches it about 4.4 miles (out-and-back) with roughly 800 feet of elevation gain, rated moderate. The nearest town is Port Alsworth. That describes the route as documented, not conditions on the day — check with Lake Clark National Park & Preserve (NPS) for closures and current conditions.
Summer (Jun-Sep). Waterfall flow swings enormously with snowmelt and recent rain, so a fall that roars in spring can be a trickle by late summer.
